DENVER (CBS/AP) — Peyton Manning was magnificent in his final regular-season tuneup Sunday, throwing his first two touchdown passes for the Denver Broncos in a 29-24 loss to the San Francisco 49ers.

Manning completed 10 of 12 passes for 122 yards, including TD tosses of 10 and 5 yards to Eric Decker.

After managing one TD to go with four turnovers in his first seven possessions this preseason, Manning drove the Broncos (1-2) to scores on all three of his possessions, then put on his visor with 46 seconds left in the first quarter after staking Denver to a 17-0 lead.

Alex Smith threw a 49-yard TD pass and David Akers kicked five field goals for the Niners (2-1), who outscored the Broncos’ backups 19-0 in the second half.
